Log, and OpsCenter Agent Log are available for viewing within OpsCenter monitoring.

Use the AWS CLI instead of the AWS SDK when bulk loading backups to Amazon S3
locations. Using the AWS CLI rather than the AWS SDK can result in a performance
increase, with a noticeable decrease in the time it takes to complete a backup. This
is an OpsCenter Labs feature (that is, under ongoing development but available for
use). The feature is available in OpsCenter versions 6.1.3 and later.

Note: When the AWS S3 CLI is enabled, the S3 throttling setting is ignored by OpsCenter
during backups. See Tuning throttling for
AWS CLI.

Prerequisites

Install the AWS CLI package on every node. DataStax recommends using the Amazon
bundled installer method and upgrading to the latest version of AWS CLI if it is
already installed. See Install the AWS CLI using the bundled
installer in the Amazon documentation for installation
procedures.

Tip: As a recommended best practice for OpsCenter,
install the AWS CLI bundle using APT as
follows:

Procedure

Open cluster_name.conf for editing. Substitute
cluster_name with the name of your cluster. Setting agent
options through the cluster configuration file sets the corresponding property
in address.yaml on every node.

If necessitated by your environment, open
address.yaml for editing and configure at the
node level. Do so for every node that requires a specific configuration
override.
